Burglary protection for windows + floor-to-ceiling windows on the north side

If you live in an area where break-ins occur frequently (conveniently located for gangs), RC2 is enough to deter them and procurement criminals. If you are a particular target because there are known saleable valuables (antiques, art, coins, jewelry...) in lucrative quantities, then upgrade rather. Building measures do not help against fear. By the way, only about 15% of break-ins happen at night. During the day, the grilles and shutters are hardly down in practice, right?

Thank you for your advice. - I am thinking of installing a lamp with a motion detector and camera. The problem I see is that when detected from a distance, there is little possibility to prevent it - In my opinion, the grid or roller shutter keeps the occasional burglar away - There are no valuables (building a house + property is bankrupting us) - RC3 windows are good. I feared that as soon as a burglar starts his work, he will definitely leave damage on the window regardless of whether he succeeds or not. Afterwards, I have to pay for the repair

The longer it takes to get in, the less likely the break-in is.

That is exactly the point. Only time matters...

Damages are covered by the insurance (at least mostly). Better a few scratches on the frame than a ransacked house. Roller shutters offer zero protection. They can easily be torn out. It is a persistent myth. After at most 3-5 minutes, the perpetrators give up. You need to come up with a plan on how to react when the camera detects activity and you are not there. - you can speak to the perpetrators through the camera - call the police - and even better are good neighbors. As soon as there is any movement, the burglars disappear. However, the neighbors should not confront the perpetrators to avoid getting into danger.
